Fine-tuning the climate
Synopsis
At least 10,000 aircraft would be needed to inject sulfur particles into the stratosphere every two years to reflect sunlight and cool the planet.
Synopsis
David Keith, a researcher at Harvard University, proposes a radical plan to combat climate change through solar radiation management. In Iceland, scientists turn greenhouse gases into stone, while questions arise about the risks of geoengineering. The documentary examines various interventions, from injecting sulfur into the stratosphere to cooling the planet, as experts debate the urgency and feasibility of these methods in light of escalating climate threats.

Frequently Asked Questions
What is the purpose of the Scopex project?
The Scopex project aims to create a screen using dust particles to reflect the sun's rays and weaken or halt global warming.
How much would solar geoengineering require in terms of sulfur particles?
Solar geoengineering would require injecting at least 10,000 aircraft releasing sulfur particles into the stratosphere every two years, with a quantity measured in something like a million tons a year.
What effect did the Pinatubo eruption have on global temperature?
The Pinatubo eruption in 1991 caused the global temperature to drop by 0.4°C.
